HAND-STAMP FOR INDORSING, SLC.

:SPECIFICATION forming part of Letters Patent N o. 741,520, dated October 13, 1903. Application filed J une 20, 190i. Serial No. 657,311. (No modelJ' To @ZZ whom t wtayconcern:

Be it known that I, EUGEN JOHANNES MAN- KIEwIoZ, a subject of the Emperor of Germany, residing at Hamburg, lin the Empire of Germany, have invented certain new and usefulImprovements in anew or Improved Hand- Stamp for Indorsin'g and the Like, of which the following is a full, clear, and exact'description. Y

Thisinvention consists ofanew orim proved hand-stamp the special feature of which is that a number of different stamping-plates are so arranged on an endless band or hinged together in series that the particular stampA which it is desired to use can be readily brought into position and its designation observed by means of an indicator.

A further feature is an automatic inking device which inks the particular stamp in 5 an arrangement for controlling the movement of the endless band.

The casing within which the stamp works consists of an upper part a, in combination with a lower part b, into Which it is adapted to slide by a telescope action. Upon the movable part a are mounted two parallel rollers c d, over which is arranged an endless band or the like carrying stamping-plates 1, 2, 3, 4, dac., bearing any suitable and various denominations. Each stamping-plate is repeated or indicated upon a register or indicator hfand an endless 4chain f, passing over toothed wheels onfthe axles of the twoY rollers aforesaid, carries a pointer g, which not only serves to rotate the endless band and bring any desired stamp into position, but also indicates by its position on the register or indicator the exact stamp which is for the moment ready for impressing. The wheels of the rollers over which the chain f passes are so proportioned to the diameter of Fig. 4 is a side view of ,the whole device seen from outside, and Fig.

the rollers c CZ that the whole series of stampn ing-plates can make a complete circuit while the pointer g simply moves from the top to the bottom of the indicator or register h, for which purpose one of the toothed wheels over which the chain passes must be an idle wheel. The rollers c d are, as will be seen, flattened into hexagonal or similar form suited to the stamping-plates. v

Inorder to efficiently'stop the bottom roller when a stam ping-plate has been brought into position and prevent Vthe same from revolving further or accidentally becoming displaced, a nut t is fixed upon the end of the axlel of similar section to the roller and a pairof flat spring-arms o bear against the same,` thus producing a restraining effect. If the spring-arms themselves be of rigid material,'they may be arranged scissorwise, with a compression-spring u between their ends.

The inking of the particular stamp about tobe used is done by an inking-roller Z, mount ed: between the extremities of the long ar'ms of a pair of bell-crank levers k, hinged to a pivot-rod t', lying across the lower casing vb, so that every time the upper casing ais forced down the roller Z inks the bottom stampingplate. The short arms of the bell-crank levers carry a wheel m, which is continually pressed upon by springs n, fixed into the back of the lower casing `b. The arrangement of the inking-roller Z is such that while the complete hand-stamp is not in the act of stamping said roller Z remains immediately behind the stamping-plate waiting to be inked. At the extreme ends of the roller are two raised rims o, of elastic material, which bear against the lower edges of the upper casing a. Upon the lowering of the latter the roller Z rotates by reason of the rolling of the elastic rims o upon the lower edges of the upper casing a and rolls under pressure of springs n upon the under surface of the stampingfplate, thusinking the latter. When the inking'of the plate is over, the further descent of the upper casing a causes the inking-roller to continue its horizontal movement along the bottom edge of the walls a of the upper casing and to ride upon its elastic rims around the corner and up along the side edges, when its arm will be in a vertical position, as shown by Fig. 3. After the stamping has been per- IOO formed the pressure upon the upper casing is released, when the springs 'n return the arms 7c to their original position (shown in Fig. 2) by bearing upon the Wheels m, carried by short arms of bell-crank lever lo, and the upper casing rises to its full height under the influence of springs o", situated between it and the lower casing b.

The manner of using the apparatus is, brieiy, as follows: Should it be desired to use the stamp No. 7, for example, the endless chain fis rotated by means of the pointer g being traveled up or down until it is opposite the space 7 on the indicator. When this is done, the corresponding stamp 7 is at the bottom of the series in position for use.

NVhat I claim, and desire to secure by Letters Patent, is

l. In a hand-stamp for indorsing and the like of the kind in which a series of printingsurfaces is arranged in an endless band, the combination of two rollers c and d, of an indioator or register h on the outside of the apparatus, an endless chain f passing over toothed wheels, one of said wheels being fixed on the axle of one of said two rollers, and a pointer g carried by the said chain adapted to indicate or readily bring into position any desired stamping-plate, the whole substantially as described with reference to the drawings. v

2. In a hand-stamp for indorsing and the like, the combination of an endless band bearing stamping-surfaces, two parallel rollers over which said band is arranged, a toothed wheel at the extremity of one of said rollers, a chain f passing over said toothed wheel for the purpose of rotating said rollers, together with said band when desired, a pointer g fixed on the chain and an indicator h upon the oasing, the diameter of the toothed wheel aforesaid being so proportioned to the corresponding roller that the whole series of printingsurfaces on the endless band are capable of being brought into proper position for printing by the single traverse of the pointer from the top to the bottom of the indicator, the whole substantially as described.

In witness whereof I subscribe my signature in presence of two witnesses.
